Apparel and hospitality brands — not other banks — define the shape of The Northern Trust Company's nearest audiences. Across the top 10 neighbors, similarity scores (a measure of how closely two entities' audiences resemble each other in composition) range from 0.92 down to 0.87, with no single dominant outlier pulling far ahead of the rest — the hallmark of a broad shape.

Tommy Bahama leads at 0.92, followed closely by J. McLaughlin at 0.92 and Autograph Collection Hotels at 0.91. Curio Collection (0.90) and Boutique & Specialized Lodging (0.89) extend the hospitality cluster, while Saint Laurent (0.89), vineyard vines (0.89), Four Seasons Hotels and Resorts (0.88), and Gucci (0.88) fill out a mix of apparel and luxury lodging. WSJ Mansion (0.87), a real estate news publisher, is the only non-apparel, non-hospitality entity in the top 10. By subcategory, the top 10 breaks down as five Apparel entries (General, Womens Apparel), four Hospitality & Lodging entries (Luxury Hotels, Boutique and Specialized Lodging), and one News Publisher. UBS Group, the one fellow bank in the broader neighbor set, doesn't appear until position 18 at 0.82 — well outside the top 10.

The pattern points to an audience whose shape is defined more by luxury lifestyle consumption than by financial services affinity.
